Data expressed in median [interquartile range] or number (percentage). ABI: ankle brachial index; PAD: peripheral arterial disease. ABI was classified as follows: normal from >0.9–1.3, ≤0.9 PAD, <0.4 severe PAD, and >1.3 noncompressible vessel [11]. In one patient left ABI could not be estimated due to history of amputation.
